These are carbon fiber 540 and glass fiber 450 isobas (fishing rods). The 5.4 is an Iso No. 2. There is a crack in the guide ring, and the fixed guide on the ho-mochi (middle section of the rod) comes off, so it has been repaired with Aron Alpha (super glue). The 4.5 is a Chinu Kouchou (sea bream hard action). Thank you.
